My invention relates to building construction, and particularly to anew and novel door stop as applied to door frames.

With the gradual increase in the use by the trade of metal frames for openings, the use doors has likewise increased.

of metal p v However, it has been found that a metal door closing upon an outstanding metal door stop will produce considerable noise and will,

A in time, become very annoying to those oc cupied in close proximity to the door.

A number of expedients have been devisedV the use of metal to overcome this objection to for the door frames, all more or less efficient purpose intended. j

An object of my invention is to provide a metal door frame having a resilient block, p

or a plurality of resilient blocks, in the door contacting face of the door vstop to absorb the force of the blow 'against the stop.

A further object of my invention is to provide resilient blocks that may be adjusted relative to the projection beyond the face of the stop so as to insure a satisfactory result regardless of the amount of wear upon the block.

My invention will be more readily understood by reference to the accompanying drawings, in which Fig. 1 is a perspective view of a door opening showing the door frame of my construction; a

Fig. 2 is a horizontal sectional view, slightly enlarged, showing the device of my construction and invention;

Fig. 3 is a vertical sectional view of the door stop, and l Fig. 4 is a horizontal sectional view showing the door stop before the screw is inserted.

By reference to the accompanying drawings, A, and mortar B with the metal door frame 10, having the anchors 11 and plaster defining and terminal portion 12, the specific details of which have copending applications.

The face of the frame 10 is formed into the door stop 13, extending the length .of the frame member 10. At a suitable point on 5 the door contacting face of the stop I provide flow where it will project it will be seen that I have shown a wall been disclosed in prior a pocket for the reception of the lresilient vblock "14. Thepecket-may be formed in any suitable manner, but preferably as shown, by bending inwardly the ears 15e-16 of the door contacting face of the stop 13. Y A U-sh'aped band 17 is utilized within the stop to join the two ears 15-16 and thus provide a pocket for the block 14. f

The block 14 placed within the pocket is of any suitable shape, preferably the shape of the aperture in the door stop, and is provided with an opening which extends through the length thereof. Beforey the block 14 is inserted within the pocketprovided therefor, an expansion bolt 18 is forced therein, ytogether with thescrew 19 for the exansiony thereof.

The initial position of the resilient block 14 is shown best in Fig. 4 where the block is simply inserted within the pocket and is notl anchored therein. Y Figs. 2 and 3 show the block with the expansion bolt 18 in panded position, thus forcing the block against the walls 16.-17 of the pocket.'

It is evident that the block 14 will be firmly anchored within the pocket after only a few of the block out of the pocket as desired.

Additional expansion of the bolt 18 will cause the material composing the blockv tov beyond the face of the. stop. Thus adjustment can readily be made by a few turns of the screw 19 when the top of the block wears 0H in use.

' It is obvious that various modifications and variations maybe made'in the construction herein disclosed, within thejskill of the mechanic, and I do not wish to be limited except as indicated in the appended claims.

VI claim:

1. In metal door frame construction, the combination of `a metal jamb and door stop formed on the face thereof, means integral with said stop forming a pocket in the doorcontacting face of said stop, a resilient block disposed within said pocket, a portion of which projects beyond the face of said stop, means for effecting the expansion of said block in said pocket for anchoring said block within said pocket.

2. In metal door fraine construction, the combination of a metal jainb and door stop formed on the face thereof, means integral With said stop forming a pocket in the door contacting face of said stop, a resilient block disposed Within said block, a portion of which projects beyond the face of said stop, 'and means within said block, comprising a threaded bolt and an expansion socket for securing said block Within said pocket and for permitting adjustment of said block re1ative to the amount of projection thereof.

In testimony whereof I have afIiXed my signature.
